I find that reverb helps 70-80% of the time to give fx and dialogue the ambience that I need, but stereo delays will definitely help you get that last little bit if reverb doesn't quite get it.
With Premiere and Audition/Pro Tools, the presets really are great starting points too, you just usually need to reduce them or toy with them a bit.

It looks like, according to Atomos, it gets up to 4:2:2 8bit 4k (vs.10bit internal 4:2:0 in 4k). Hope that helps!
You mention price point a few times, but don't actually mention the price in the review. For ease, could you add that in somewhere?
When I shoot a more formal interview, I always go with the interviewer to the side of the camera. If I'm doing an interview in the moment, with the camera on my shoulder and I have a sound guy, I'll have the sound guy stand where I would and have the subject direct their answer to the sound guy after I ask. Sometimes if I am soloing a shoot and have a camera+minishotgun and maybe a LAV on my shoulder, I'll have the subject look at my face. It's not ideal in the sense that they are almost looking at the lens, but it's better than them feeling uncomfortable answering while pretending I'm over a foot or two.
That said, my approach is to always let the subject(s) tell the story. It's for this reason I avoid recorded voiceover, as well as having my voice in it. Being able to draw the story out from what is said in interviews and observationally makes things so much more powerful. Not that either of those are bad, that's just what I feel works best for me.
